DatapacksJava
Age Switch
Allows you to change the age of mobs using a name tag. Naming them “Baby” turns them into babies, while “Adult” restores their adult form.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This datapack adds a fun mechanic that lets you change a mob’s age using name tags. Renaming a mob as “Baby” transforms it into its baby form permanently, even if renamed again. The only way to reverse the effect is by using another name tag named “Adult.” Perfect for players who want to build farms, zoos, or simply add a more dynamic and adorable touch to their world.
